This starting mode is used when it is necessary to limit the maximum starting
current. This can be adjusted for 50 to 500% of full load amperes as shown in
Figure 3.6.

Refer to Figure 3.7.
1. Starting Time – Set switches 7–9 according to the time desired. For example,
if you want current limit active for 30 seconds, switches 6 and 9 would be ON
and switches 7 and 8 would be OFF
2. Kickstart Time – Set Kickstart Time rotary digital switch to OFF
3. Current Limit/Soft Start – Switch 6 must be ON in the current limit mode.
Set Current Limit rotary digital switch accordingly. For example, if you want
to restrict the starting current to 300% of full load amperes, set rotary switch to
position 5
4. Energy Saver Select – Set switch 5 ON if you want the energy saver feature
(or OFF if you do not want this feature active)
5. Auxiliary Contact Select – Set switch 4 OFF if you want “normal” auxiliary
contacts, ON if you want “up-to-speed” auxiliary contacts
6. Stall Select – Set switch 3 ON if you want the stall feature (or OFF if you do
not want this feature active)
NOTE: For resistive load operation, switch 3 and 5 must be OFF
